Find n(A) for the set.
1) A = 200, 201,
202, ..., 2000)
A) n(A)= 1801
B) n(A)= 4
C) n(A)=2000

Answers

Answer 1

A=200,201,202.........,2000

Here, it forms an AP with common difference 1

Let the number of terms in the set be n

[tex] T_{n} = a+(n-1)d \\\\ 2000= 200+(n-1) \\\\ 200+n-1= 2000 \\\\ => n=2000-199= 1801[/tex]

Hence,n(A)=1801

Tell whether the angles are complementary or supplementary. Then find the value of $x$ . A ray intersects two other rays forming a right angle. The angles formed after the intersection is x degrees and left parenthesis x minus 20 right parenthesis degrees.

Answers

The measure of the value of x is 55°.

We have,

Complementary angles are two angles that add up to 90 degrees.

Supplementary angles are two angles that add up to 180 degrees.

Now,

The ray intersects two other rays forming a right angle.

This means,

It is a complementary angle.

i.e

x + (x - 20) = 90

x + x - 20 = 90

2x = 90 + 20

2x = 110

x = 55°

Thus,

The measure of the value of x is 55°.

What value of b will make the equation a true statement? Explain how you arrived at your solution. (−34 + 43)+ b = 0

Answers

Answer:

b = -9

Step-by-step explanation:

Given the equation (−34 + 43)+ b = 0

We are to find the value of b

First solve for the value in parenthesis

(−34 + 43)+ b = 0

9+b = 0

Subtract 9  from both sides

9+b-9 = 0 - 9

b+0 = -9

b = -9

Hence the value of b will make the equation a true statement is -9

Diagonals of a parallelogram bisect each other

Plot the points.

We see the diagonals are:

(-2,-1) (6,3)  and (1,3), (3,-1)

The midpoint of any diagonal is the intersection of the diagonals.

Use midpoint formula to find the coordinates:

x = (x₁ + x₂)/2 = (-2 + 6)/2 = 4/2 = 2y = (y₁ + y₂)/2 = (-1 + 3)/2 = 2/2 = 1

Answer:

x = 7

Step-by-step explanation:

A triangle's total interior angle measurement will equal 180°.

Set all measurements equal to 180:

(82) + (9x - 6) + (6x - 1) = 180

Simplify. Combine like terms:

(82 - 6 - 1) + (9x + 6x) = 180

(82 - 7) + (15x) = 180

(75) + 15x = 180

Next, isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

~

First, Subtract 75 from both sides of the equation:

15x + 75 = 180

15x + 75 (-75) = 180 (-75)

15x = 180 - 75

15x = 105

Next, divide 15 from both sides of the equation:

(15x)/15 = (105)/15

x = 105/15

x = 7

7 is your value for x.

A student’s AP statistics project involves comparing the time it takes a student to complete a set of 25 basic trinomial factoring problems while listening to either rap music or country music. Twelve students are timed on two different sets of problems of equal difficulty. The order of which set of problems he does first and which music he listens to first are randomized. The resulting data is thus paired, with each student acting as his own "pair." Which of the following conditions is required to perform a t-test on these paired data?
A. The distribution of times for all students on each set of problems must be approximately Normal.
B. The distribution of times for all students while listening to each type of music must be approximately Normal.
C. The distribution of times for all 24 sets of problems (12 students are taking 2 tests each) must be approximately Normal.
D. The distribution of differences between each individual student’s times on each of the two tests (time with rap – time with country) must be approximately Normal.

Answers

Answer:

D. The distribution of differences between each individual student’s times on each of the two tests (time with rap – time with country) must be approximately Normal.

Step-by-step explanation:

For a paired test, there are two measured values of a particular point, here what is measured is the time taken for each of rap and country music by each student.

The difference :

t2 - t1 = time with rap music - time with country music.

The number of samples usually associated with t distribution is usuall y very small (n ≤ 30).

10^7 = 10000000

next, solve for the distances the sun is from Jupiter and Mars,

10^8 = 100000000

1.42x100000000=142000000 miles

4.84x100000000=484000000 miles

next, subtract the distances

484000000-142000000=342000000 miles

then, divide the sum by 93000000 to find the amount in astronomical units.

342000000/93000000=3.677419
